Abstract (en)

[origin: EP0336691A2] A thermal transfer printer is provided for reproducing an original gradated image comprising a plurality of image elements which have individual gradations in the form of a printed image comprising a plurality of image elements and having an image density determined by the number of image elements printed per unit section. A latch circuit (1) receives and latches an input train of image bit data representing the gradations of the image elements of the original image. A data processor (2-5) converts the latched image bit data into a train of binary image bit data representing the image density of the original image to be reproduced. A printing unit (6) is arranged to receive the train of binary image bit data representing the image density of the original image to be reproduced and is operative selectively to print individual image elements such that the image density of the printed image is represented in terms of the number of image elements printed per unit section. <IMAGE>
